This was an actual sign that I saw written in black marker on brown cardboard hanging in the back window of a new Kia Spectra. From the way the person was driving, she really didn't need the sign to explain. The herky-jerky start and stop like a bumper car or someone you've woken from a dead sleep. It was nice of her to warn us though. Most drivers aren't that considerate.
It made me wonder two things: 1) When do I stop becoming a new stick driver and start being an old stick driver? and 2) How many more ways can I let you made rude references without saying something obvious about fun pointing?
